Sooo easy

I know I'm right

 

How did you get that?

 

Not all of us looked in the comments. This problem is not too hard ;)

Half of 2 = 1 and 100 - 1 = 99.

 

Thought it might trick people because people think of the first as a ratio of 1:2 and they get the answer when the sister is 100 as a ratio of 50:100. People get 50 as their answer

 

Besides a lot of people get tricked so I thought maybe some people are looking at the comments

 

Lol I was joking

 

99 obv

 

Underscores are subscripts but I cant be bothered lol

 

What's 9 times 999

 

99 years old.

 

Let's just stop this madness xD

 

First of all, you wouldn't be alive when your 100 but it you do the answer is 99.

 

How do you know? Have you seen the future?
